......!!!!!!!!...................................
14:33:17 ** The square root of a negative will often give you an error (what can you square to get a negative, since any number squared is positive?), but on certain calculators it gives a complex number (actually two complex numbers). These are not real numbers; for the purposes of this course there is no real square root of a negative number. There is no real number that can be squared to give a negative. If you square a negative number you get a negative times a negative, which is positive. If you square a positive number you get a positive number. So a negative number has no real square root. **
......!!!!!!!!...................................
RESPONSE --> I didn't realize that the problem was asking for the square root of a negative. I see what this is asking and realize that you cannot find the square root of a negative number. self critique assessment: 2

14:35:51 ** 204 / 18 = 11 with remainder 6. If we had 11 drawers they would hold all but 6 of the tapes. The leftover tapes also have to go into a drawer, so we need a 12th drawer. **
......!!!!!!!!...................................
RESPONSE --> 204 tapes divided by 18 compartments and then a remainder of 6 tapes. There are some tapes left over so they need to go into a 12th drawer. self critique assessment: 1
